Question

Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R
Assertion A: Leaves exposed to the Sun, are thinner, have larger area of lami have more chlorophyll and less stomata.
Reason R: Plants become structurally and physiologically adapted to the amount of solar radiations received.

• A. Both A and R are correct and R is the correct explation of A
• B. Both A and R are correct but R is NOT the correct explation of A
• C. A is correct but R is not correct
• D. A is not correct but R is correct

Hint:

Sun Leaves = THICKER, smaller lami area, dense stomata, thick cuticle (prevents water loss).
Shade Leaves = THINNER, broader lami area, higher chlorophyll content (captures maximum light).

Answer 1

The Correct Option is D
